Soft 404 errors occur when a web server returns a 200 OK status code for a page that Google identifies as non-existent, empty, or an error page. This mismatch creates confusion for search engine crawlers because the technical header indicates the content is available, while the visual content suggests the opposite. To maintain high search visibility and index quality, you must ensure your server returns a true 404 or 410 code for deleted content.
What is a soft 404 error?
A soft 404 is not an official HTTP status code but a label Google assigns to specific URLs during the crawling process. In a typical scenario, when a user visits a page that does not exist, the server should send a 404 (Not Found) or 410 (Gone) status code. These codes tell Googlebot that the page is intentionally missing and should be removed from the search index.
However, some servers are configured to send a 200 OK code even when the page is empty or displays a ‘Page Not Found’ message. When Google encounters this, it sees a page that claims to be valid but offers no value to users. This results in the page being flagged as a soft 404. It essentially means the technical signal and the content reality are in conflict.
Why does Google flag 200 OK pages as soft 404s?
Google aims to provide the best user experience by excluding low-quality or non-existent pages from search results. If a search engine indexes a page that says ‘Sorry, this product is no longer available’ but has a 200 OK status, users who click that result will be frustrated. Google monitors the visual elements, the text volume, and the overall structure of the page to determine if it is a ‘real’ page or a placeholder.
Another reason involves crawl budget efficiency. Search engines have limited resources for crawling a website. If a site has thousands of soft 404s, Googlebot wastes time processing ‘dead’ pages instead of discovering new, valuable content. By flagging these as soft 404s, Google signals to the site owner that the technical configuration needs correction to prevent ranking issues.
How do you fix soft 404 errors in Google Search Console?
The primary tool for identifying these issues is Google Search Console. You should navigate to the Indexing section and click on the Pages report. Here, you will find a list of reasons why pages are not indexed. If your site has these issues, you will see a ‘Soft 404’ category. Clicking on this category reveals the specific URLs Google has flagged.
- Inspect the URL using the Search Console Inspection tool to see how Googlebot renders the page.
- Check if the page is truly missing or if it just has very little content.
- Verify the HTTP status code using a header checker tool or the ‘Live Test’ feature in Search Console.
- Determine if the page should be restored, redirected, or permanently deleted.
- Update your server configuration or CMS settings to return the correct status code.
Analyzing thin content issues
Sometimes a page is flagged as a soft 404 simply because it does not have enough unique text. For instance, a category page on a WordPress blog that only lists one short post might trigger this. In this case, the fix is not to delete the page but to add more helpful content. If the page is a valid part of your site structure, ensure it has descriptive text, images, and internal links.
Common causes of soft 404 errors on e-commerce sites
E-commerce platforms like Shopify or Magento frequently encounter soft 404s due to inventory changes. A common pattern is when a product goes out of stock and the platform displays an empty product page. If the server still returns a 200 OK code, Google will likely flag it. A similar issue occurs with internal search result pages that return no products but still show the site’s header and footer.
Another frequent cause is the use of automated redirects. Some site owners set up scripts that automatically redirect any broken URL to the homepage. Google explicitly states that redirecting irrelevant URLs to the homepage is a soft 404 pattern. This is because the homepage is not a direct replacement for a specific product or article, and it confuses users who expected different content.
Why redirecting to the homepage is a bad strategy
Redirecting all broken links to your homepage might seem like a way to preserve link equity, but it often backfires. When Google sees a 301 redirect to a page that is not related to the original content, it treats that redirect as a soft 404. This means the ‘ranking power’ of the old URL is not passed to the homepage anyway.
Instead of a blanket redirect, you should aim for relevancy. If a specific blue running shoe is no longer sold, redirect that URL to the general ‘running shoes’ category. If there is no relevant replacement, it is better to let the page return a 404. This tells Google to stop trying to index that specific URL, which cleans up your site’s search footprint over time.
How to choose between 404 and 410 status codes?
When content is gone and will not return, you should use 404 or 410 status codes. While both tell Google that the page is missing, they carry slightly different weights in terms of speed of removal from the index. In a typical account, using either is better than a soft 404, but choosing the right one can help with faster site cleanup.
- Use a 404 (Not Found) for pages that might return in the future or if you are unsure.
- Use a 410 (Gone) for content that is permanently removed, such as a discontinued service or an old promotional page.
- Ensure your custom 404 page provides helpful navigation links to keep users on your site.
- Check your .htaccess or Nginx config files to set these codes at the server level.
- Monitor the ‘Crawl Stats’ report in Search Console to see how quickly Google acknowledges the changes.
Fixing soft 404s caused by technical glitches
Technical errors in your site’s template can also trigger these flags. For example, if a PHP error prevents the main content from loading but the header and footer still render, the server might still send a 200 OK code. Googlebot sees a page with no main text and assumes it is an error page. Regularly checking your server logs for 5xx errors can help identify the root cause of these invisible content failures.
For sites using JavaScript frameworks like React or Angular, ensure that the server-side rendering (SSR) is correctly configured. If the initial HTML sent to Google is empty because the JavaScript hasn’t executed yet, Google might misinterpret the page as a soft 404. Testing your URLs with the Search Console ‘Rendered HTML’ view will show exactly what Googlebot sees during the crawl.
Where to start this week
Begin by opening Google Search Console and navigating to the ‘Pages’ report under the Indexing section. Look for the ‘Soft 404’ status in the table. If you find URLs listed there, pick the top five with the most impressions and inspect them individually. Determine if they are truly missing or just thin on content.
If the pages are missing, update your server settings to return a 404 code instead of a redirect to the homepage. If the pages are valid but thin, add at least 200-300 words of relevant content and a few images to signal to Google that the page provides value. Once you have applied the fixes, use the ‘Validate Fix’ button in Search Console to notify Google that the URLs are ready for re-crawling. At Alien Road, we often see that cleaning up these errors leads to a more efficient crawl and better overall indexing for the remaining high-quality pages.
